NAT with TWO WAN interfaces [SOLVED]
Hello pfSense Forum
I have what I thought would be a fairly straight forward set up, but trying to use NAT on two interfaces is giving me some head ache.
The basics of my config
LAN INT: 172.16.0.1
WAN: 173.11.311.311 (obfuscated to no workie)
OPT1: 173.228.411.411 (same)
I have NAT mapping working BEAUTIFULLY on my default WAN (WAN) interface. If I attempt to set up port forwards for NAT by-way-of OPT1, I can see SYN_RCVD connections form outside host, but the route back seems to get lost, thinking that it is something to do with the default route being on the WAN.
If I packet cap on each interface, this is what I see:
IP 173.228.441.441.80 > 18.104.22.168.15903: tcp 0 (The 173.228 addr is the addr o the OPT1 interface!!!)
IP 22.214.171.124.28647 > 173.228.411.411.80: tcp 0 (This is the inbound to NAT traversal
IP 10.48.70.10.80 > 126.96.36.199.56322: tcp 0 (10.48.XX.XX is my internal dest host that currently shows the SYN_RCVD)
I would be happy to provide more info, just wasn't sure where to stop and where to begin.
Thanks for any thoughts in advance!
OPT1 was missing gateway declaration in OPT1 Interface settings.
Once I defined the next hop router (towards cloud) as the gateway, NAT worked.
